Ka of C6H5CO2H is 6.5 x 10-5.
Ka = [C6H5CO2][H3O]/[C6H5CO2H]
6.5 x 10-5 = x2/(0.461 - x)
after manipulation
X2+ (6.5 x 10-5)x - (2.99 x 10-5)
--> Plug in the Quadratic Formula
X = +/- 0.0055
[H3O] = 0.0055
-Log(0.0055) = pH
pH = 2.26

∙ 13y agoTo determine the pH of the solution, you need to first calculate the concentration of H+ ions by considering the dissociation of the acid using the Ka value. Then, use the equation pH = -log[H+] to find the pH. After performing the calculations, the pH of the 0.461 M C6H5CO2H solution with a Ka of 6.5 x 10^-5 is approximately 2.1.
105 degrees Celsius = 221 degrees Fahrenheit
105 kilograms is equal to 231.49 pounds.
105 tons is equal to 210,000 pounds.
105 kilograms is approximately 231.5 pounds, and 3704 ounces.
105 cm is equal to 41.34 inches.
The address of the Cemeteries Of Athens Preservation is: 105 Park Street, Athens, TN 37371-0461
If you mean: 7x+21 = 105 Then the solution is: x = 12
105/6 = 35/2
105 Celsius
m = -19

The same as the square root of positive 105, multiplied by i (the imaginary unit). So, the answer will be approximately 10.25i. If only real numbers are acceptable, then there is no solution.
That's an improper fraction - the solution is 1 & 1/15
The least common multiple of 63, 105, and 2142 is 10,710.You can determine this by looking at the multiples of each number individually and seeing when they match:63: 63, 126, 189...10,710105: 105, 210, 315...10,7102,142: 2142, 4284, 6426, 8568, 10,710
Volume = 35 ft*105 ft*140 ft = 35/3 yds * 105/3 yds * 140*3 yds = 19055.55... cubic yards.
-35y-134 = -29 -35y = 134-29 -35y = 105 y = -3
105+105=210.
